ABSTRACT:
A method and an apparatus for acquiring a target frequency of a multi-path signal are disclosed. The multi-path signal includes a first path signal and a second path signal. First, the first path signal is received through a first path and the second path signal is received through a second path. Then, a target region is determined. The target region is a portion of a second cyclic prefix in the second path signal which overlaps with a first cyclic prefix in the first path signal. Afterward, the target frequency is determined based on the target region.
